Considering what's happening to Sweden I don't know how you can say that unless you're in complete denial, even then as well I wouldn't call it a form of socialism to begin with. People keep doing this and it annoys the crap out of me, they keep referencing various European countries as 'successes' of Socialism or the sneakier term 'democratic socialism'.

It's gotten so obnoxious that even in Denmark their prime minister debunked it and said they were not 'socialist' they were a market economy.

After seeing his country held up as an example in the US presidential debate, Danish Prime Minister Lars Løkke Rasmussen used an address at Harvard to explain the Nordic model to a US audience suddenly very interested in Denmark.

It's very easy to claim your favourite ideology as a success when you just redefine everything to suit your arguments.
